For purposes of disclosure the invention is herein illustrated as. mountedv in. position in a combination. door 20- having a main frame 2|., and withinthe lower portions of this main frameL Ziirpermanent panel sections 22 are afforded. Inthe. `uppersection of. the main frame 2|, a rectangular opening 23`- is` `aiorded. within. which areplaceable. closure panel.l 25 may be mounted.

In. Fig.. 1, thisclosure.A panel. 25. is` illustrated as.

constituting a` storm sash. panel and. in. accordancewith usual practice; asimilar screen panel is-affordediwhich maybesubstituted-for the panel 2-5 at appropriate seasons ofthe year. The'panel 25. includes a rectangular frame 25j, andv this rectangular frame may be moved in what will be termed anl outer direction into the opening 23 to engage aI shoulder 26 that isf formed on the. frame 25| about theopening 23 at the-outer side of the door. The. panel 25=is held in thisposition. and against the shoulder 26 by aplurality of latch structures 30 and it is to suchlatch structures that the present invention pertains.

The latch structure 3i) ina broad sense embodies an elongated latch arm 3'l that is disposed within thearcuate slot 32 that is formed in the outer side edge of the frame 25'F; and this' armj is adapted to be rotated about an axis that is perpendicular'to the forward face of the panel 25 until the outer end of the latching 4 arm A3l' enters into and engages with aJ generally similar arcuate slot 33 formed in the inner edge of the opening 23 of the frame. The latch arm 3| is supported within the slot 32 by an operating member 35 that is extended into the slot 32 transversely thereof through a bore 36 that is extended from the front of the frame of the panel 25 and into the slot 32. The operating member 25 is held in position axially within the bore 36 by a retaining member 40 as will hereinafter be described in some detail.

The three elements 3|, 35 and 40 that constitute each latch 30 are under the present invention adapted for production by the rapid and economical processes of sheet metal stamping. Thus, the latching arm 3| is formed from sheet metal in a generally at form having parallel side edges 3|S and rounded end edges 3|E. One end of this arm 3| is formed so as to provide for quick and easy association with the operating member 35, and for this purpose the arm 3| has a non-circular opening 4| formed therein. The opening 4| as herein shown has parallel sides 4|S and arcuate ends 4|E which are so sized and related that they afford a ready and easy means for effecting a rotative interlock between the operating member 35 and the latch arm 3|, as will be described in detail hereinafter. It will also be noted that at its other end the arm 3| is formed to afford similar cam surfaces 3| C that are symmetrical with respect to the longitudinal center line of the arm, and these cam surfaces 3|C are afforded for camming cooperation with the slot 33 so as to assure tight clamping of the panel 25 against the shoulder 26.

The operating member 35 is of generally cupshaped form to aiord a cylindrical side wall 35W and end wall 35E, and the joining corner between these walls has a substantial radius so as to facilitate the forming operation. The end wall 35E has a diametric slot 35S formed therein of a size adapted to receive the end of a screw driver, thus to provide for imparting rotative movement to the member 35. The cylindrical wall 35W has its other end formed to afford two longitudinally extending lugs 35L that constitute partial continuations of the wall 35W and are diametrically spaced. The width of the lugs 35L and the diameter of the wall 35W are so related to the size and form of the opening 4| that the lugs 35L will fit into the opening 4| adiacent to arcuate ends 4IE and with the side edges of the lugs 35L closely adjacent to the sides 4|S of the opening 4|. This t is reasonably snug and affords a mounting for the latch arm 3| as well as a rotation-transmitting connection between the operating member 35 and the latch arm 3|.

The retaining member 4|) is also formed by stamping to afford a cylindrical wall 40W of the same diameter as the wall 35W and at one end this wall 40W has a iiat or Washer-like flange 40F extended outwardly therefrom and in a plane disposed at right angles to the axis of the wall 40W. At spaced points about the edge of the flange 40F, pointed anchoring teeth 40T are formed so as to extend from the flange 40F in the same direction as and parallel to the wall 40W, and these teeth are of a length that is less than the length of the wall 40W for purposes that will appear hereinafter.

It will be apparent that the three elements 3|, 35 and 40 of the present latch device are all adapted to be made from sheet metal by the economical processes of Sheet metal stamping, and it will also be evident that these elements of the present latch device may be readily and easily put in place on a door panel or the like, and the latch arm thereof may be readily operated through latching and non-latching movements.

Thus, in the installation of the latch device of the present invention, the slot 32 is so located in the edge of the frame 25 that the outer side of the slot is spaced from the inside face of the frame 25F, the lower side as viewed in Fig. 4 consitituting such inside door face, that this spacing is equal to the combined lengths of the operating member 35 and the retaining member 40. With this relationship, the driving of the retaining member 43 into position as shown in Fig. 4, serves to locate the ends of the lugs 35L in engagement with or relatively close to the remote or outer side of the slot 32 as shown in Fig. 4, and this assures that the latching arm 3| will be properly engaged with and supported by the lugs 35L at all times. The bore 36 is preferably made of such a size that the sleeves or cylindrical walls of the retaining member 40 and the operating member 35 have a snug fit within the bore 36.

After the slot 32 and the bore 35 have been formed, the inner end of the latch arm 3| is inserted into the slot 32 with the cam surfaces 3|C facing toward the inner side of the frame in which the bore 36 is provided, and the operating member 35 is inserted as shown in Fig. 4 into the bore 36 and the lugs 35L are extended through the opening 4| in the arm 3|. This movement of the operating member 35 is continued until the ends of the lugs 35L are engaged with or are closely adjacent to the outer side of the slot 32 as shown in Fig. 4. When this has been done, the latch arm 3| is supported in position by the lugs 35L of the operating member 35 and the engagement of the lugs 35L with the opening 4| is such that a rotative driving or operating connection is afforded between the operating member 35 and the latch arm 3|.

The retaining member 40 is then put in place, and it will be noted that the sleeve or wall section 40W is somewhat longer than the anchoring teeth 40T so that the projecting end portion of the wall 40W may be inserted into the outer end of the bore 36 to properly locate the retaining member 40. When the anchoring teeth 40T have engaged the adjacent face of the frame 25F, these anchoring teeth 40T may be driven into the frame 25F, and when the inner face of the flange 40F engages the face of the lframe 25F, the projecting end of the wall A40W will be engaged as shown in Fig. 4 with the end wall 35E of the operating member 35, thus to hold the operating member 35 in the proper axial position wherein it supports the latch arm 3 I. It Will be observed that when the retaining member 40 is thus in position, the cylindrical wall 40W aords a clearance space through which a screw driver may be inserted for engagement with the slot 35S to latch or un-latch the mechanism.

As shown in Fig. 4, it will be observed that the slot 33 is offset slightly in an outward direction from the slot 32 so as to assure that the cam surfaces 3|C will engage the inner face of the slot 33 and the other side or corner of the slot 32 with a camming action, and this, of course, causes the arm 3| to bear firmly against the outer side of the slot 32 and the inner side of the slot 33, thus to draw the frame 25E firmly into position in an outward direction against the shoulder 26.
